Hello there, soldier. I got a job that's a little too easy for my guys. But you'll do fine. Hey, don't get pissy, I don't know you that well yet to give you a normal job! There's a lot of bandit scum roaming the streets. They don't bother me much, but they're still a nuisance. Calm down, say, five of them, and get a couple of MP-133 shotguns off them. I think that'll be enough for you. Dismissed, soldier!
So, you got the job done, great. Probably just bought the shotguns off some trader for cheap, huh? Well, whatever, I don't really care. You brought the shotties and that's what matters.
Enter any map and search for and kill five Scavs whom can be found throughout the map. Be sure to check if they have the MP-133s. This shotgun can be found on Scavs, inside various Searchable Containers, or simply lying around. They must be in a functional state to be handed in. To hand over the shotguns, go to the Traders menu, then to Prapor and click on the "Tasks" tab. Here you should see the "Turn In" button to hand over the shotguns.
